DETAILED DESCRIPTION

[0021] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0022] like Figure 1 , 2As shown in Figures 3 and 4, a multifunctional backpack comprises a backpack body 101, a pair of shoulder straps 102 are arranged on the backpack body 101, a take-in and put-out opening 103 is arranged on the top of the backpack body 101, a connecting zipper 104 adapted to the take-in and put-out opening 103 is arranged on the top of the backpack body 101, a handle 105 is also arranged on the top side end of the backpack body 101, a flexible electric heating interlayer is also arranged inside the side wall of the backpack body 101, a battery 106 electrically connected to the flexible electric heating interlayer is also arranged on the rear side end of the backpack body 101, and a temperature controller 107 is also arranged on the battery 106. The front and rear side ends of the bag body 101 are respectively detachably provided with semi-storage boxes 108, a flexible connection sleeve 109 with a top opening of a take-and-place hole 117 is provided between the two semi-storage boxes 108, a plurality of connection tubes 110 are respectively provided at the front and rear side ends of one semi-storage box 108, and a connection rod 111 is also provided at the front and rear side ends of the other semi-storage box 108, which is respectively telescopically plugged with the plurality of connection tubes 110, and the plurality of connection tubes 110 are also provided with connection bolts 112 that can abut against the outer side walls of the corresponding connection rods 111 to fix the connection between the connection tubes 110 and the connection rods 111. The flexible electric heating interlayer is a carbon fiber heating wire layer, and the connection bolts 112 are hand-tightened bolts.

[0023] like Figure 3 , 4 As shown, the outer side walls of the two half storage boxes 108 are respectively provided with a plurality of sub-buckles 115, and the inner side walls of the backpack body 101 are respectively provided with female buckles 116 adapted to the plurality of corresponding sub-buckles 115. Through the cooperation of the plurality of sub-buckles 115 and the plurality of female buckles 116, the first half storage box 108 and the second half storage box 108 can be flexibly and conveniently fixed together with the backpack body 101.

[0024] The user can open the zipper to separate the multiple sub-buckles 115 from the corresponding female buckles 116, thereby taking out the two semi-storage boxes 108 and the flexible connecting sleeve 109 from the backpack body 101 through the access port 103, and then loosen the connecting bolts 112 to release the fixation of the connection between the connecting tube 110 and the connecting rod 111. Then, the expansion and contraction amount of the connecting rod 111 in the connecting tube 110 can be adjusted according to the amount of items to be stored, and then the connecting bolts 112 can be retightened, so that the storage space formed by the two semi-storage boxes 108 and the flexible connecting sleeve 109 meets the user's needs for storing items; through the cooperation of the connecting tube 110 and the connecting rod 111, it is also possible to effectively prevent the storage space formed by the two semi-storage boxes 108 and the flexible connecting sleeve 109 from being easily deformed when subjected to external pressure, thereby storing the internal items more intactly.

[0025] Afterwards, the plurality of sub-buttons 115 can be re-fastened and connected with the corresponding female buttons 116, and the connecting zipper 104 can be closed. Afterwards, the flexible electric heating layer can be activated by the temperature controller 107 to heat the interior of the backpack body 101, thereby heat-insulating and storing the items.

[0026] When there is no need to store items, the thickness of the storage space formed by the two semi-storage boxes 108 and the flexible connecting sleeve 109 can be reduced by increasing the telescopic amount of the connecting rod 111 in the connecting tube 110, thereby reducing the overall thickness of the device and allowing users to store the device more conveniently.

[0028] According to another embodiment of the present invention, Figure 1 As shown, the storage battery 106 is also provided with an alarm buzzer 114 for alarming when the power level drops to a threshold of 10%. Through the alarm buzzer 114, the user can promptly learn that the power level of the storage battery 106 has dropped to a threshold of 10%, thereby replenishing the storage battery 106 with electric energy in a timely manner.

[0029] According to another embodiment of the present invention, Figure 1 , 2 As shown, the backpack body 101 is also provided with a limiting plate 201 corresponding to the zipper head 203 of the connecting zipper 104 in the closed state, and a limiting screw rod 202 capable of being plugged and fixed with the zipper head 203 of the connecting zipper 104 is screwed on the limiting plate 201. After the connecting zipper 104 is closed, the zipper head 203 of the connecting zipper 104 can be clamped and fixed with the limiting plate 201, and then the limiting screw rod 202 is adjusted by rotating relative to the limiting plate 201, so that the inner side end of the limiting screw rod 202 is plugged and fixed with the zipper head 203 of the connecting zipper 104, thereby preventing the zipper head 203 of the connecting zipper 104 from sliding autonomously, and further preventing the connecting zipper 104 from opening autonomously.

[0030] According to another embodiment of the present invention, Figure 2 As shown, the outer end of the limit screw rod 202 is also provided with a screw block 204. Through the screw block 204, the limit screw rod 202 can be easily turned and adjusted, so that the limit screw rod 202 can easily realize or release the plug-in limit fixation of the zipper head 203 of the continuous zipper.

[0031] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
